Key Histogram
In the genre of KPOP, the most prevalent keys are C sharp, F, and G, as indicated by the plots. Conversely, in KRnB, the histogram reveals that the A and G key is favored among other keys.
In KPOP, the prevalence of C sharp, F, and G keys mirrors their common usage in Western pop music, suggesting a shared musical influence between the two genres. Conversely, within KRnB, the dominance of the A and G keys underscores the unique tonal preferences characteristic of Korean R&B music. These trends underscore the dynamic interplay between cultural influences and genre-specific characteristics, illustrating how musical styles can both converge and diverge across different contexts.
Keygrams for songs in different keys
Now lets look at the keygrams.
In looking at the keygrams of the most popular songs in the corpus, some interesting patterns emerge regarding their tonal centers.
For instance, when looking at the song in the key of D, we notice that the confidence for D minor key dominates, which suggests a strong association with that tonality. But what’s really interesting is that the confidence for C sharp minor key pops up even more frequently than for D minor. This might be because of some connection between D minor and C sharp minor keys. The keys share some of the same notes, which could explain why C sharp minor shows up so prominently alongside D minor.
Now, the keygram of the song in G key is a bit more straightforward. It’s clear that both G minor and major keys rule the roost throughout the song, indicating a strong focus on G as the tonal center. Also interesting to note: there are a couple of moments in the song where the keygram isn’t too sure about which key it’s in, besides the usual uncertainty at the beginning and end of songs. These moments of uncertainty could signal shifts in harmony or brief changes in tonality within the song.

Chromagram Comparison
I selected two songs from the corpus based on their energy and loudness scores provided by Spotify. One of the songs is “LIMBO” by keshi, which scores low in both energy and loudness. The other song is “Talk That Talk” by TWICE, which scores high in both energy and loudness.
When comparing the chromagrams of these songs, the differences are quite apparent. “Talk That Talk” is notably higher in tempo compared to “LIMBO.”
In terms of musical composition, “Talk That Talk” employs a wider range of notes and chords whereas “LIMBO” maintains a simpler structure with a clear emphasis on the G sharp/A flat note.
Regarding the data from the Spotify API, it seems less confident in identifying the notes used in “Talk That Talk” compared to “LIMBO.” This could be attributed to the greater variability in the composition of “Talk That Talk.”
Overall, these observations underscore how songs can differ significantly in their energy, and musical complexity, as perceived by listeners.
Introduction
I’ve put together a collection of playlists that represent my taste in music, particularly focusing on KRnB and KPOP genres. These playlists consist of four categories: two are tailored to my personal preferences in KRnB and KPOP, while the other two feature more general KRnB and KPOP tracks. The selection of these playlists is based on my deep love for KRnB and KPOP music.
The personal playlists are curated by Spotify, using my listening history to tailor the content to my tastes. On the other hand, the broader KRnB and KPOP playlists are popular among a wider audience.
With this collection, I aim to analyze and understand the differences between KRnB and KPOP. I’m also interested in exploring why I prefer certain KPOP and KRnB tracks over others. This analysis will help me gain insights into my music preferences and the unique characteristics of these genres.

Energy Distribution
In this plot I pulled in data of 4 different playlists:
Let’s first look at the personal playlists by selecting that option in the plot legend.
What we see is that, on average, KPOP songs tend to have higher energy levels compared to KRnB. But there’s a catch – there’s some overlap between the two genres. This means that a KRnB track could have the energy level typical of a KPOP song, and vice versa. It goes to show that energy level is just one factor among many that define a song’s genre.
Now, when we switch over to the general playlists, things look different. The songs seem more spread out across energy levels compared to the personal playlists. This suggests that personally, I might have a specific energy level in mind when picking KRnB or KPOP songs for my playlists. It’s all about personal taste and what vibes with me the most.
Acousticness Comparison
Looking at the plot, it’s clear that KRnB songs tend to have higher acousticness compared to KPOP tunes. There’s just a small sliver of overlap between the acousticness of KRnB and KPOP tracks. Also, notice how the range of acousticness for KRnB songs is wider than that of KPOP. This suggests that KRnB artists have more leeway in using different instruments compared to the more structured sound of KPOP.
Description
In the plot, you can clearly see how energy and loudness are linked, especially with that regression line slicing through the data points. There’s also this faint boundary line that seems to separate KPOP and KRnB songs. Oh, and there’s this one standout: the KPOP hit “Cupid” by Fifty Fifty, chilling in the KRnB zone for loudness and energy. Just hover over the point to check it out!
